Description
Technical field
This utility model relates to a kind of therapeutic instrument of tinnitus, particularly relates to a kind of tinnitus therapeutic apparatus be integrated by test-and-treat.
Background technology
Tinnitus is the supervisor Auditory Perception of people's ear when the external voice not having to respond stimulates, and is one of modal dysacousis.Common tinnitus sound has squeak, chirp and the tinkle of bells etc., and tinnitus sound is sustainable or step existence.Many patients may hear more than a kind of sound.Tinnitus can occur suddenly or slowly occur, shows obvious heterogeneity, and 1000 tinnitus patients may describe out 1000 kinds of different sound, and its tone and intensity of sound may be also different.The sickness rate of tinnitus is high, the adult of about 10% ~ 15% be all subject to its tire out.Further, tinnitus also can bring many harm, as negatively in insomnia, anxiety, depression and attention disorders etc. clear becomes main puzzlement, even can affect the every aspects such as patient work, family and social activity.
The diagnosis and treatment of tinnitus are the tinnitus diagnosis made according to the subjective audio experience of patient; Tinnitus treatment is carried out in the result according to tinnitus diagnosis.
The core of tinnitus diagnosis is that tinnitus is detected, and namely utilizes the acoustic characteristic of tinnitus to make the diagnosis of each tinnitus patient " characteristic ", and this is also the prerequisite of tinnitus treatment.Tinnitus detects four psychoacoustic characteristics mainly comprising tinnitus: suppress after tone (i.e. frequency), loudness, minimum masking level and remnants.The key that tinnitus is detected carries out tinnitus coupling fast, efficiently and accurately.
At present, the tinnitus matching process of main flow mainly contains two kinds: first " sonometer method ": as the term suggests namely use sonometer to try out immediate tinnitus frequency in certain sequence one by one with reference to the method for pure tone test, debug loudness size more further.Second " binomial forced choice method ": the coupling of first carrying out loudness, matches the loudness from the every third-octave point of 500 ~ 16000Hz respectively; Then carry out the coupling of frequency, namely give the pure tone of two different frequencies at every turn, allow patient select, closer to one of its tinnitus frequency, so to find immediate frequency; Finally carry out octave confusion test.Wherein, " sonometer method " relies on constantly to attempt finding out final frequency, consuming time longer, simultaneously because the identification of people's ear to different pure tone is limited, so its reliability is not good yet.And " binomial forced choice method " is although reach certain reliability, but still there are some problems: one, select from given two frequencies at every turn, if select higher frequency, then tinnitus frequency is limited at the scope of more than higher frequency, if select lower frequency, then tinnitus frequency is limited at the scope of below lower frequency, probability between two frequencies is appeared in order to reduce tinnitus frequency, two frequency intervals at every turn provided can not be too large, this also indirectly limits change step, result in matching efficiency lower; Its two, select each time all tinnitus frequency range to be divided into 1/2 of current frequency range, this just causes once select mistake, tinnitus frequency will be divided into mistake frequency range and cannot jump out.Therefore, the fault-tolerance of " binomial forced choice method " is lower.
Because the cause of disease of tinnitus is complicated, pathogenesis is not bright, the means of tinnitus treatment are also in development in pluralism.Tinnitus treatment compares several aspects such as common are the naturopathy such as medicine and brain stimulation, sonic stimulation, psychological counselling and surgical operation.Wherein, the majority such as brain stimulation, laser therapy is considered to invalid; Surgical operation is also only applicable to the tinnitus that some organic diseases cause; Further, also do not ratify at present effectively or tinnitus is had to the medicine of direct curative effect; Psychological counselling has become the basic ingredient of tinnitus treatment; Sonic stimulation various informative, early stage tinnitus is sheltered and acclimatization treatment adopts noise and natural phonation, attempts, with a kind of sound " replacement " tinnitus sound, to reduce the awakening to tinnitus, but tinnitus can't be allowed to weaken or disappear.
By the progressively understanding of the neural connection of corresponding tinnitus mechanism, expedite the emergence of series of new sonic stimulation form.Current report effectively mainly contains following several:
1. the special trap music therapy centered by tinnitus frequency: it, by filtering out the music scope of an octave centered by tinnitus frequency, cuts down the energy of this part;
2. neural music therapy: it, by reducing the annular of tinnitus thus reaching tinnitus desensitization, treats similar with acclimatization;
3. neural desynchronization modulation: use the short rope above and below tinnitus frequency to stimulate at random, increase for auditory center spontaneous discharge and the region of paradoxical discharge, the synchronicity desynchronization that neuron is increased, reaches the effect that auditory center is reinvented;
4. modulate the in short-term suppression of sound realization to tinnitus: within the scope of research discovery 6000 ~ 9000Hz, the amplitude modulation of 40Hz can realize the effective suppression to tinnitus;
5. sonifer and artificial cochlea: reduce tinnitus degree by compensating the auditory deprivation in hearing loss region, curative effect does not have a concluding.
Based on above several sonic stimulation strategy, current tinnitus treatment product has: Acoustic co-ordinated resetneuromodulation
and
zen.Wherein, first two treatment product corresponding neural desynchronization modulation and neural music therapy respectively;
in utilization 4, independently selectable arrowband and wide interval frequency hopping sound channel play Sound stimulat;
zen is then that the commercial prod be widely used---sonifer is only listened.These four kinds commercial tinnitus treatment equipment almost reach absolute technical monopoly and price fixing to domestic tinnitus treatment market, and meanwhile, because lack large clinical randomised study, its curative effect is also indefinite.
Same kind of products at abroad listens Buddhist nun
(Tinni
) be also the more product of current domestic application, the tinnitus treatment pattern adopted is based on masking treatment, the sound can selected for patient has tens kinds of natural phonations and light music, utilize extraneous sound to force to suppress cochlea or the acous spontaneous excited acquisition strengthened, make a lot of patient can't hear tinnitus when masking treatment.Under the tinnitus neuro physiology pattern of Jastreboff, this therapeutic instrument disappearance in conjunction with tinnitus acclimatization treatment concept utilization tinnitus masking treatment tinnitus can meet a part of clinical demand, the unhealthy emotion impact that link is acted on behalf of because of tinnitus.But due to the increase of industry, environment and public place of entertainment noise exposure water product, aged tendency of population is increasingly sharpened, because the high-frequency balance caused by noise deaf, presbyacusis, sudden sensorineural hearing loss and high frequency tinnitus patient get more and more, this part huge patient group often can not tolerate tinnitus and shelter; Secondly, for the patient that tinnitus sound is larger, need higher volume to reach sheltering of tinnitus, this not only can not relief of tinnitus on the contrary because excessive noise increases the weight of hearing loss and even increases the weight of tinnitus.
In addition, in existing tinnitus treatment, be all often carry out the frequency of tinnitus and the detection of loudness by detecting instrument, then according to testing result, carry out tinnitus treatment again by tinnitus treatment instrument.This certainly will bring very large inconvenience for tinnitus treatment.

Embodiment 1
Present embodiment discloses a kind of tinnitus detection method, as shown in Figure 1, comprising:
Step S10, detects the pure tone audiometry of ears:
Different people, the pure tone threshold of its ear is different; Further, be just same person, the pure tone threshold of its left ear and auris dextra is also different.Therefore, in the present embodiment, need to carry out pure tone audiometry detection respectively to the left ear of patient and auris dextra, obtain the pure tone audiometry of left ear and the pure tone threshold of auris dextra respectively.
In the present embodiment, the method for pure tone test is adopted to detect the pure tone audiometry of patient's ears.In audition audiometric room, play test tone to patient, patient judges that sound the most softly that its left/right ear can be heard just is exactly the pure tone threshold of left/right ear.
Step S20, according to pure tone threshold, adopts 3 forced choice methods to carry out the tinnitus frequency match of tinnitus ear, obtains the tinnitus frequency of tinnitus ear:
The frequency of sound determines the tone of sound: tone is high, then sound is light, short, sharp or thin; Tone is low, then sound is heavy, long, vexed or thick; And the loudness of sound determines the height of sound.
In existing tinnitus detection technique, be all often adopt first to mate Tinnitus volume, tinnitus frequency is being mated.But so in fact and do not meet the psychology of seeing a doctor of patient.Many times, due to the problem that the audition of tinnitus patient is in fact too not large, therefore it is often paid close attention to more to the frequency of tinnitus.If first mated the Tinnitus volume of patient, patient often because the sound oneself heard the tinnitus tone of not sum oneself is different, produces in subconsciousness and repels psychology, be not easy to treatment.Therefore, in the present embodiment, first tinnitus frequency is mated.
Further, all left ear of detection of tinnitus frequency and Tinnitus volume and auris dextra are separately carried out.
Further, in the present embodiment, adopt 3 forced choice methods of computer automation to carry out the coupling of tinnitus frequency, the matching process of its tinnitus frequency as shown in Figure 2, comprising:
Step S21, selects test ear:
If the audition of patient's two ears is all good, when so tinnitus detection being carried out to tinnitus ear, just another non-tinnitus ear (namely testing ear) is played sound, so that patient is more prone to the sound identifying tinnitus.Certainly, also have a kind of situation to be that the non-tinnitus ear of patient can't hear sound, so to tinnitus ear carry out tinnitus detect time, be directly using tinnitus ear as test ear, it is played sound, carries out tinnitus detection, to obtain tinnitus frequency.
Step S22, play three pure tones to test ear at the above 10dB ~ 20dB of its pure tone threshold, the frequency of three pure tones is respectively: 2000Hz, 4000Hz and 8000Hz:
In the present embodiment, first the test ear of patient is play to the pure tone of three different frequencies.Wherein, these three pure tones are all more than the pure tone threshold of test ear, with the test ear one the ensureing patient pure tone play of uppick surely.Further, three pure tones are play from small to large according to frequency.In addition, in order to more be convenient to the selection of patient, to three pure tone repeat playing three times, and the broadcasting of each pure tone has certain duration, and all has an interval when adjacent pure tone is play.In the present embodiment, the duration that each pure tone is play is 500ms, and interval is 1s.
Step S23, from three pure tones, select with tinnitus ear tinnitus closest to pure tone:
Three pure tones that patient hears according to test ear, compare with the tinnitus of test ear, thus select the immediate pure tone with tinnitus.
Step S24, by determining tinnitus frequency range closest to the frequency of pure tone:
If the frequency closest to pure tone is 2000Hz, the so upper limit of tinnitus frequency range third-octave lower than 4000Hz;
If the frequency closest to pure tone is 4000Hz, so the lower limit of tinnitus frequency range is than 2000Hz high third-octave, upper limit third-octave lower than 8000Hz;
If the frequency closest to pure tone is 8000Hz, the so lower limit of tinnitus frequency range third-octave lower than 8000Hz.
In the present embodiment, octave or octave point all refer to octave within the scope of hearing frequencies or octave point.The hearing frequencies scope of the present embodiment adopts 125Hz ~ 16000Hz.
Step S25, judges the third-octave point in tinnitus frequency range:
If the third-octave point in tinnitus frequency range is less than or equal to three, so using the frequency closest to pure tone as primary election tinnitus frequency, and jump to step S26;
If the third-octave point in tinnitus frequency range is greater than three, so need the scope reducing tinnitus frequency further: i.e. the pure tone of optional three frequencies on third-octave point again from small to large in tinnitus frequency range, and compare with the tinnitus of tinnitus ear and obtain closest to pure tone, and again obtain tinnitus frequency range according to closest to pure tone, and again jump to step S25, judge the third-octave point in tinnitus frequency range.
Step S26, carries out frequency multiplication confusion test to initial tinnitus frequency, determines described tinnitus frequency:
In the present embodiment, arriving final tinnitus frequency at least has two kinds of approach, as shown in Figure 3, therefore after the initial tinnitus frequency of acquisition, also needs to carry out frequency multiplication to initial tinnitus frequency and obscures experiment, to determine the tinnitus frequency of tinnitus ear.
Frequency multiplication is obscured experiment and is comprised the pure tone that the pure tone of playing described initial tinnitus frequency and two mid frequencyes adjacent with initial tinnitus frequency are third-octave point, from these three pure tones, and confirmation tinnitus frequency further.
In order to be more convenient for illustrating, as shown in Figure 3, in step S22, Fa, Fb and Fc are respectively to the frequency of 3 pure tones that non-test ear is play, and Fa=2000Hz, Fb=4000Hz, Fc=8000Hz.So, if the pure tone that frequency is Fa is closest to pure tone, then tinnitus frequency range is limited at the scope of below Fb, and namely tinnitus upper frequency limit is the Frequency point of third-octave lower than Fb, i.e. 3180Hz; The third-octave point comprised in the frequency range of below 3180Hz is greater than three, so 3 pure tones of next optional group change to 1/4Fa, 1/4Fb, 1/4Fc, i.e. 500Hz, 1000Hz, 2000Hz.By that analogy: if the pure tone that frequency is Fb is closest to pure tone, then tinnitus frequency range is limited at the scope between Fa to Fc, namely the upper limit is the Frequency point of third-octave lower than Fc; Lower limit is the Frequency point than Fa high third-octave, i.e. 2520Hz ~ 6340Hz.If frequency is the pure tone of Fc is closest to pure tone, then tinnitus frequency range is limited at the scope of more than Fb, namely tinnitus lower-frequency limit is than the Frequency point of Fb high third-octave, the frequency of 3 pure tones that next optional multicast is put changes to 4Fa, 4Fb, 4Fc, i.e. 8000Hz, 16000Hz, 32000Hz, because hearing frequencies scope is at 125Hz ~ 16000Hz, therefore, the pure tone that next multicast is put is only 8000Hz and 16000Hz two.Repeat said process again, until third-octave point in tinnitus frequency range little with equal three, the frequency so closest to pure tone is exactly initial tinnitus frequency.
Automatization's 3 forced choice methods improve the frequency interval between the pure tone selecting broadcasting, test step-length is risen to two octaves, greatly reduces the testing time.Further, as can be seen from Figure 3, the third-octave point between the frequency of every two pure tones has two kinds of paths to reach, and not only increases fault-tolerant ability, also solves tinnitus frequency if there is the problem causing omission between pure tone frequency.
Step S30, with tinnitus frequency for benchmark, carries out the Tinnitus volume coupling of testing ear, obtains the tinnitus sensitivity threshold of test ear:
The Tinnitus volume coupling of the present embodiment, specifically as shown in Figure 4, comprising:
Step S31, play the first pure tone of the different sound intensitys from small to large of more than the pure tone threshold of tinnitus frequency, the second pure tone and the 3rd pure tone to test ear, wherein, the sound intensity between two adjacent pure tones is spaced apart D:
In the present embodiment, first the test ear of patient is play to the pure tone of three different sound intensitys: the first pure tone, the second pure tone and the 3rd pure tone.These three pure tones are all more than the pure tone threshold of test ear, further, three pure tones are play from big to small or from small to large according to loudness, adjacent two pure tones the sound intensity be spaced apart D, in the present embodiment, the sound intensity interval D of usual original adoption is 5dB.In addition, in order to more be convenient to the selection of patient, to three pure tone repeat playing three times, and the broadcasting of each pure tone has certain duration, and all has an interval when adjacent pure tone is play.In the present embodiment, the duration that each pure tone is play is 500ms, and interval is 1s.
Step S32, from the first pure tone, the second pure tone and the 3rd pure tone, selection and tinnitus ear tinnitus are closest to pure tone:
Three pure tones that patient hears according to test ear, compare with the tinnitus of tinnitus ear, thus select the immediate pure tone with tinnitus.
Step S33, judges sound intensity interval D:
If D=1dB, be so the loudness matching value of tinnitus ear closest to the sound intensity of pure tone, the loudness matching value that the tinnitus sensitivity threshold of tinnitus ear equals tinnitus ear deducts the pure tone threshold of test ear.Because everyone initial audition (pure tone threshold) is different, so can not simply the sound intensity closest to pure tone be gone to demarcate as the sound intensity testing ear tinnitus, need to take into full account all correlative factors, so the tinnitus sensitivity threshold of tinnitus ear to be used as the end product of the Tinnitus volume coupling of tinnitus ear.
If D is greater than 1dB, so closest to pure tone as the second pure tone, D-1 will be spaced apart according to the sound intensity between adjacent two pure tones, reselect the first pure tone and the 3rd pure tone; And test ear is play to the first pure tone, the second pure tone and the 3rd pure tone and jumped to step S32.
The tinnitus detection method of the present embodiment substantially reduces the time of tinnitus coupling, adds fault-tolerant ability, effectively reduces the probability that the tinnitus frequency of prior art existence is undetected.
The step of various method divides above, just in order to be described clearly, can merge into a step or splitting some step, being decomposed into multiple step, when realizing as long as comprise identical logical relation, all in the protection domain of this patent; To adding inessential amendment in algorithm or in flow process or introducing inessential design, but the core design not changing its algorithm and flow process is all in the protection domain of this patent.
